Locating the serial number Serial numbers are 17-digits long following “S/N” and contain letters and numbers. Wave Music systems.

To the OP - I genuinely appreciate the heads-up, but what resulted was disappointing at best. The rant below is 100% directed at Waves and how they need to get their act together.

OK, I thought this might be worth the trouble, but I have given up. Let me preface this by noting the fact that it is 2012, not 1998. Form 49b In Excel Format more. Yep, this seems obvious, but let me tell you how this went for me. I registered for the promotion, and it did not go well. It takes a few tries before I finally get a response of 'Due to overwhelming demand, our servers are running at maximum capacity. Therefore, your OneKnob Louder free serial number has not yet been created.'

This ain't exactly the cutting edge of online promotions or order fulfillment here. We're talking about a relatively small subset of the population (musicians that have recording gear that are interested in a Waves plugin and are aware of the promotion), and we're talking about something that is not exactly computing resource intensive (generating a key). Ok, whatever. I'll trudge on. A couple of days go by, and I get another email from the computationally challenged Waves folks: Your OneKnob Louder free serial number is: 3700XXXXXXXXXX You will need to register it to your Waves account, download, install, and activate it.
